TECHNICAL FILED
Embodiments of the present invention relate to a reflective
assembly, a backlight module and a display device.
BACKGROUND
With consistent and rapid development of liquid crystal (LC)
display industry, various new types of LC products are emerging out
of the old ones. LC display panel is a kind of non-self-luminous
display panel and hence requires a light source provided by a
backlight module to achieve its function of display. The backlight
module can be classified into an edge-lit type and a direct-lit
type, depending on a location of the light source arranged therein.
The light source of the direct-lit type backlight module is
disposed right below the LC display panel to allow a relatively
higher light source density of the LC display panel, thus LC
display products incorporated with such kind of backlight module
are mostly applied in displays with strict requirements on
brightness, such as display screen of computer and LC TV.
As illustrated in FIG. 1, for a direct-lit type backlight module
well-known in the art, a reflective plate 20 having a
two-dimensional structure is placed horizontally at a planar state
on a back plate 10, which allows light emitted from a light source
30 being reflected uniformly. However, the light at an area
adjacent to an edge of the reflective plate 20 is relatively
weaker, which makes it possible that the display panel 50 has image
brightness smaller at the edge area than a central area, which will
lead to non-uniform brightness and also influence the display
effect.
SUMMARY
In one aspect, at least one embodiment of the present invention
provides a reflective assembly comprising a first reflective plate
and a second reflective plate disposed along an edge of the first
reflective plate, wherein the second reflective plate is inclined
towards a direction facing away the first reflective plate with
respective to a plane perpendicular to the edge of the first
reflective plate, and wherein a reflective surface of the first
reflective plate and a reflective surface of the second reflective
plate are located at a same side.
In one example, the first reflective plate and the second
reflective plate are connected integrally.
In one example, both the first reflective plate and the second
reflective plate are formed as a planar structure, and the
reflective surface of the first reflective plate and the reflective
surface of the second reflective plate have an included angle

In one example, the first reflective plate is formed as a planar
structure, while the second reflective plate is formed as a
cambered structure; and the first reflective plate and a tangent
line of any point on the second reflective plate have an included
angle equal to or larger than 90.degree..
In one example, the first reflective plate is a rectangular
reflective plate; and the second reflective plate comprises four
reflective sub-plates which are connected to four sides of the
first reflective plate, respectively.
In one example, portions of adjacent reflective sub-plates that are
close to each other have an overlapped area.
In one example, at least one of the reflective surface of the first
reflective plate and the reflective surface of the second
reflective plate is provided with an optical dot.
On another aspect, at least one embodiment of the present invention
further provides a backlight module comprising a light source and a
reflective assembly; wherein the light source is disposed at a side
of the reflective assembly where the reflective surface of the
first reflective plate is located.
In one example, the backlight module further comprises a back plate
and an optical film; wherein the reflective assembly is disposed
between the back plate and the optical film.
In one example, the backlight module further comprises a supporting
structure configured to support the light source, wherein the
supporting structure is arranged to penetrate through the
reflective assembly to be fixed at the back plate.
In one example, the light source comprises a plurality of light
emitting diodes arranged in an array; wherein the plurality of
light emitting diodes is disposed between the reflective assembly
and the optical film.
In one example, the plurality of light emitting diodes is disposed
at a location in correspondence with a location of the first
reflective plate of the reflective assembly.
On yet another aspect, at least one embodiment of the present
invention further provides a display device comprising a display
panel and a backlight module; wherein the backlight module is
implemented with any of the above-illustrated backlight
modules.
The reflective assembly as provided by embodiments of the present
invention comprises a first reflective plate disposed at a central
area and a second reflective plate disposed at an edge area so that
the reflective effect at the edge area can be improved by inclining
the second reflective plate towards a direction facing away the
first reflective plate with respective to a plane perpendicular to
the edge of the first reflective plate; In this way, when the
reflective assembly is applied in a backlight module to provide a
display panel with a backlight source, the arrangement of the
second reflective plate can effectively enhance the reflective
effect at the edge area so as to improve display brightness thereof
to be uniform with the central area, which overcomes the defect
that the display brightness of well-known display panels always is
relatively weaker at the edge area and relatively stronger at the
central area, thereby achieving a uniform display.

according to the embodiments of the present invention will be
described clearly and completely as below in conjunction with the
accompanying drawings of embodiments of the present invention. It
is to be understood that the described embodiments are only a part
of but not all of exemplary embodiments of the present invention.
Based on the described embodiments of the present invention,
various other embodiments can be obtained by those of ordinary
skill in the art without creative labor and those embodiments shall
fall into the protection scope of the present invention.
Unless otherwise defined, all the technical and scientific terms
used herein have the same meanings as commonly understood by one of
ordinary skill in the art to which the present invention belongs.
The terms, such as "first," "second," or the like, which are used
in the description and the claims of the present application, are
not intended to indicate any sequence, amount or importance, but
for distinguishing various components. Also, the terms, such as
"a/an," "one," or the like, are not intended to limit the amount,

thereof listed after these terms, but not preclude other elements
or objects. The terms, "on," "under," or the like are only used to
indicate relative position relationship, and when the position of
the object which is described is changed, the relative position
relationship may be changed accordingly.
As illustrated in FIGS. 2-4, embodiments of the present invention
provide a reflective assembly 200 comprising a first reflective
plate 201 and a second reflective plate 202 disposed along an edge
of the first reflective plate 201, wherein the second reflective
plate 202 is inclined towards a direction facing away the first
reflective plate 201 with respective to a plane perpendicular to
the edge of the first reflective plate 201, and wherein a
reflective surface of the first reflective plate 201 and a
reflective surface of the second reflective plate 202 are located
at a same side of the reflective assembly 200.
It should be explained that, first of all, the reflective assembly
200 as provided by embodiments of the present invention is
generally applied in a backlight module. In practical
implementation, the reflective assembly 200 has to be fixed by
placing the first reflective plate 201 horizontally at a planar
state on a back plate, so the first reflective plate 201 in one
example is formed as a planar structure; based on which the second
reflective plate 202 can be formed as a planar structure or a
cambered structure, without details defined particularly herein;
wherein the cambered structure can comprise a convex structure as
illustrated in FIG. 7A or a concave structure as illustrated in
FIG. 7B.
Secondly, the first reflective plate 201 can have a shape of
rectangular or oval or alternatively other shapes of course,
without details defined particularly herein; based on which the
edge of the first reflective plate 21 can have a shape designed
varyingly depending on the shape of the first reflective plate 21
per se, but the plane perpendicular to the edge of the first
reflective plate 201 will be always perpendicular to a plane where
the first reflective plate 201 lies. In this way, the second
reflective plate 202 is inclined towards a direction facing away
the first reflective plate 201 with respective to the
above-mentioned plane perpendicular to the edge of the first
reflective plate 201, at an inclined angle which is not
particularly defined herein, as long as it allows achieving the
desired reflective effect. For example, given the plane
perpendicular to the edge of the first reflective plate 201 as the
reference plane, inclining towards the direction facing away the
first reflective plate 201 is interpreted as "inclining outwardly"
in FIGS. 2-4, while inclining towards the direction approaching the
first reflective plate 201 is interpreted as "inclining inwardly"
in FIGS. 2-4.
Thirdly, in some examples the first reflective plate 201 and the
second reflective plate 202 of the reflective assembly 200 can be
connected integrally, while in some other examples the first
reflective plate 201 and the second reflective plate 202 are
connected independently (i.e., connected as two separate members),
without details particularly defined herein. Based on which the
first reflective surface of the first reflective plate 201 and the
reflective surface of the second reflective plate 202 can be made
of a same material or made of different materials, without details
particularly defined herein.
In one example, the reflective surface of the first reflective
plate 201 and the reflective surface of the second reflective plate
202 can be made of a material having high reflectivity; for
example, the material can be metal or alloy material such as
silver, aluminum, gold, chromium, copper, indium, iridium, nickel,
platinum and tin, or can be white paint vehicle resistant to
xanthation and heat, without limiting the present invention
thereto; instead, it can be any material well-known in the art to
have excellent reflective effect as well as stable physical and
chemical properties.
As above, the reflective assembly 200 as provided by embodiments of
the present invention comprises a first reflective plate 201 and a
second reflective plate 202 disposed along an edge of the first
reflective plate 201, wherein the second reflective plate 202 is
inclined towards a direction facing away the first reflective plate
201 with respective to a plane perpendicular to the edge of the
first reflective plate 201, and wherein a reflective surface of the
first reflective plate 201 and a reflective surface of the second
reflective plate 202 are located at a same side of the reflective
assembly 200.
In practical implementation where a backlight module serves to
provide a display panel with a backlight source, the display panel
always has brightness weaker at an edge area than a central area
thereof. However, according to embodiments of the present
invention, the reflective assembly 200 comprises a first reflective
plate 201 disposed at the central area and a second reflective
plate 202 disposed at the edge area (that is, disposed at the edge
of the first reflective plate), so that the reflective effect at
the edge area of the reflective assembly 200 can be effectively
improved by configuring the second reflective plate 202 to be
inclined towards a direction facing away the first reflective plate
201 with respective to a plane perpendicular to the edge of the
first reflective plate 201; in this way, when the reflective
assembly 200 is applied in a backlight module to provide a display
panel with a backlight source, the arrangement of the second
reflective plate 202 can effectively improve the reflective effect
at the edge area, and hence can improve the display brightness at
the edge area of the display panel to be uniform with the central
area, so as to achieve an uniform display.
In one example, the first reflective plate 201 and the second
reflective plate 202 can be connected integrally. Herein, with an
integral structure of the first reflective plate 201 and the second
reflective plate 202, the reflective assembly 200 can be
manufactured by an integral forming process. In this way, as
compared with those reflective assemblies with non-integral
structures, it's unlikely for the first reflective plate 201 and
the second reflective plate 202 to have a gap there-between, and
the problem of uneven reflection due to a non-reflective area
existed at the portion where the first reflective plate 201 and the
second reflective plate 202 are jointed can be effectively
prevented.
In some examples, both the first reflective plate 201 and the
second reflective plate 202 can be formed as a planar structure,
and the first reflective plate 201 and the second reflective plate
202 can have an included angle between 120.degree. and
150.degree..
Of course, in another example, the second reflective plate 202 can
be formed as a cambered structure; in such case, it's only
necessary to ensure that the first reflective plate 201 and a
tangent line of any point on the second reflective plate 202 have
an included angle equal to or larger than 90.degree., that is, the
include angle is a right angle or an obtuse angle.
Based on the above examples, a manufacture process of the
reflective assembly 200 can be effectively simplified by forming
both the first reflective plate 201 and the second reflective plate
202 as a planar structure. In this way, it can not only effectively
improve reflective effect of light at the edge area of the
reflective assembly 200 but also avoids the light being reflected
by focusing on the central area, so as to achieve an uniform
display which allows the display brightness at the edge area being
uniform with the central area.
In some examples, as illustrated in FIG. 4, the reflective surface
of the reflective plate 201 and/or the reflective surface of the
second reflective plate 202 can be provided with an optical dot to
enhance the reflective effect of the reflective assembly 200. For
example, the optical dot can be printed onto the reflective surface
by printing methods after manufacture of the reflective plate, or
can be directly formed on the reflective surface by chemical
etching method, precision machining method (V-cut),
photolithography process or internal diffusing method during
manufacture of the reflective plate. The optical dot can be formed
into any shape including, for example, round, rhombus, triangle,
oval and cone, and can be formed to be raised from or concaved into
the reflective surface. For example, the optical dot on the
reflective surface of the first reflective plate 201 can be
distributed at a density identical with or different from that on
the reflective surface of the second reflective plate 202.
Herein it should be explained that, a planar structure of the first
reflective plate 201 and/or the second reflective plate 202 are/is
defined from the macroscopical aspect; in the case where the
reflective surface(s) of the first reflective plate 201 and/or the
second reflective plate 202 are/is further provided with an optical
dot, the optical dot has a dimension small enough so as not to
influence the surface structure of the first reflective plate 201
and/or the second reflective plate 202, thus the first reflective
plate 201 and/or the second reflective plate 202 provided with the
optical dot can still be regarded as having a planar structure.
In some example, as illustrated in FIGS. 2-4, the first reflective
plate 201 can be a rectangular reflective plate; and the second
reflective plate 202 can comprise four reflective sub-plates
connected to four sides of the first reflective plate 201,
respectively.
Herein it should be explained that the shape of the first
reflective plate 201 is not limited to rectangular but can have
other options such as oval; however, regardless of the shape of the
reflective plate 201, the second reflective plate 202 always has to
be connected to the first reflective plate 201 so as to prevent any
gap existed at a jointed portion between the first reflective plate
201 and the second reflective plate 202, which gap may lead to
non-uniform light reflection.
On such basis, the four reflective sub-plates of the second
reflective plate 202 can be or can be not contacted with each
other; of course, they can also be partly contacted with each
other. Embodiments of the present invention are not intended to
define particularly the contact between adjacent reflective
sub-plates.
Referring to FIG. 4, in the case where the four reflective
sub-plates are contacted with each other, portions of respective
reflective sub-plates that are close to each other can have an
overlapped area there-between. For light incident on the edge area
of the reflective assembly 200, it will return to a light emitting
side through a reflection by the second reflective plate 202; in
this way, it can ensure that the light incident on the second
reflective plate 202 is completely reflected so as to avoid any gap
area generated between adjacent reflective sub-plates, which gap
area may lead to a display failure resulted from non-uniform light
reflection.
As illustrated in FIG. 5, embodiments of the present invention
further provide a backlight module comprising a light source 30 and
a reflective assembly 200; wherein the reflective assembly 200 can
be implemented with the one described in any of the above
examples.
On such basis, the light source 30 has to be disposed at a side of
the reflective assembly 200 where the first reflective plate 201 is
located; in other words, the second reflective plate 202 of the
reflective assembly 200 is bent towards the side where the light
source 30 is located, so as to ensure that the light emitted from
the light source 30 will return to the light emitting side through
a reflection by a reflective surface of the reflective assembly
200, upon reaching the reflective surface.
Herein it should be explained that the light source 30 can be
disposed at the side where the reflective surface of the reflective
assembly 200 is located in such a manner that, for example, the
light emitting side of the light source 30 is located at the side
of the reflective assembly 200 where the reflective surface is
located, while a supporting structure configured to support the
light source 30 has to be fixed onto a back plate by penetrating
through the reflective assembly 200.
On such basis, referring to FIG. 5, in some examples the backlight
module can further comprise a back plate 10 and an optical film 40;
wherein the reflective assembly 200 is disposed between the back
plate 10 and the optical film 40. In this way, the reflective
effect of light at the edge area of the reflective assembly 200 can
be effectively improved by bending the second reflective plate 202
of the reflective assembly 200 towards the optical film 40, so as
to avoid a brightness weaker at the edge area than the central
area; in this way, light being reflected can be uniformly emitted
upon passing through the optical film 40.
For example, the optical film 40 can comprise a diffusion film, a
prism sheet, a brightness enhancement film, etc., which can be
combined in any ways according to actual demands.
According to embodiments of the present invention, the back plate
10 is configured to support respective components of the backlight
module including the above-mentioned reflective assembly 200, the
light source 30 and the optical film 40. For example, the optical
film 40 can be fixed by an adhesive frame (not illustrated), while
the adhesive frame in turn can be fixed at the back plate 10 by
engaging devices.
On such basis, in one example, the reflective assembly 200
comprises a first reflective plate 201 and a second reflective
plate 202; and wherein the first reflective plate 201 can be fixed
at the back plate 10 by a positioning pole (not illustrated) so as
to prevent the reflective assembly 200 from moving with respective
to the back plate 10.
In one example, the light source 30 can comprise a plurality of
light emitting diodes (LEDs) arranged in an array; the plurality of
LEDs can be disposed between the reflective assembly 200 and the
optical film 40. For example, the plurality of LEDs can be disposed
at a location in correspondence with a location of the first
reflective plate 201 of the reflective assembly 200, so a
brightness at an area (i.e., the edge area) to which the second
reflective plate 202 corresponds will be considerably weaker than
an area (i.e., the central area) to which the first reflective
plate 201 corresponds; on such basis, the brightness at the edge
area can be improved to be in close proximity to the brightness of
the central area by increasing the light reflection at the edge
area so as to achieve an uniform display. In this way, the
reflective assembly 200 as provided by embodiments of the present
invention can effectively increase the light reflection at the edge
area to improve the display brightness thereof to be uniform with
the central area, so as to achieve a uniform display.
Of course, cold cathode fluorescent lamp (CCFL) can also be used as
the light source 30 in embodiments of the present invention,
without any limitation thereto.
Embodiments of the present invention further provide a display
device, as illustrated in FIG. 6, it comprises a display panel 50
and a backlight module; wherein the backlight module is the one
described in any of the above examples.
Herein it should be explained that the display device can be of
non-self-illumination type such as LC display device or LC
television, and can be supplied with a backlight source by the
backlight module in embodiments of the present invention which can
effectively improve the display brightness at the edge area of the
display panel 50 to be uniform with the central area, so as to
achieve a uniform display.
